SPECIFICATION forming part Of Letters Patent N0. 640,288, dated January 2, 1900. Application filed August 22, 1898. Serial No. 689,265. (No model.)

To (tZZ whom it may concern:

Beit known thatl, CHARLES F. Hovr, a citizen of the United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented certain new and useful Improvements in Filters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to an apparatus for purifying water; and its objects are to proi'5 vide a device which may be submerged in streams, pools, lakes, or ponds and will extract the water therefrom free from all impurities, leaving the impurities in the body from which pure water is desired. This ohj ect I attain by the construction shown in the accompanying drawings, which it is now my purpose to describe.

Figure 1 is a longitudinal sectional view of my invention. Fig. 2 is a view in side elevation. Fig. 3 is a cross-sectional view. Fig. at is a plan view of my invention, and Fig. 5 is an enlarged detail view of a section of some of the parts as shown in Fig. 3. Fig. 6 is a view of a clamp or band with thumb-screw used to hold the cloth or filtering material in position. Fig. 7 is a section of Fig. 1, showing the upper left-hand corner of said figure.

Referring now to the illustrations, in which like parts are designated by similar letters of reference, Ct represents the tube or pipe through which the water is extracted from my device after being filtered.

The filter is cylindrical in shape and adapted to stand on end, as shown in Figs. 1 and 0 2, and the upper head or coverb and the lower head or base 0 are held firmly in position by means of the connecting-rods c, 0 c and 0. Inside of said rods and adjacent to the same circumscribing the device are bands P 5 and P, located at suitable distances apart and from the heads. A band 2' passes around said rods directly underneath the head i) and tends to hold the parts firmly in place when the head is removed. Inside of said bands 1? and P a rim 9', composed of heavy cloth, 5o canvas, or other suitable material for screening water, passes around said cylinder and is firmly secured at each end at the heads I) and o by means of the bands 11 and '0, respectively, Fig. 6, which pass around said cloth immediately within the cover b and base 0 and can be tightened by means of the thumbscrew '6, thus drawing the cloth firmly against the cover j and base m, presently described. lVithin said rim r a space is left for sand (15, and then another rim of cloth 6 is inserted. Adjacent to said cloth 6 is a rim of filteringpaper f, and next to said filtering-paper is another rim of cloth h. Within said last rim of cloth is a wire support orscreen g, adapted to hold the cloth and paper firmly in place and prevent water and sand from crowding the same into the space 8 left for the filtered water. A false bottom Z is placed within the base 0 at the lower end of the Waterspace, and another false bottom at occupies the bottom of the space occupied by the sand, as shown infFig. 1. Covers 70 and j, corresponding to said false bottoms, are placed 'at the top of the spaces occupied by water and sand directly underneath the head b. The rims of cloth and paper last described completely encircle the cylinder in their respective locations and are firmly secured at the ends by means of tacks w, driven through the cloth and paper into the false bottom Z and cover 70, so that no water can enter the space 8 except by percolation. The cloth and paper are thus secured before the insertion of the sand, false bottom m, and cover j. After the water 8 5 has passed through the various layers of cloth, sand, and filtering-paper into the water-space s it is thoroughly purified and can be drawn off through the pipe a by suitable mechanism, the water filling the space as fast 0 as withdrawn.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with suitable frame work having a head and base connected with suitable rods and bands, of an inner chan1- her for filtered water and an outer oompartment filled with sand,said chamber and compartment being separated by means of cloth and filteringpaper, substantially as described.

2. A water-filter composed of the following parts, viz: a pipe or, entering the filter, heads I) and 0, rods 0, 0 c and 0 connecting said heads, bands P and P, supporting the frame, cloths rand e, forming-a compartment for the sand d, filtering-papery, between said cloth 6, and another cloth h, an inner support g, inside of said layers of cloth and paper, a space 3 for the reception of filtered water, false bottoms Z and m, and covers j and It, at the ends of said spaces for sand and water, as and for the purposes specified.

3. A cylindrically-shaped framework having heads secured by rods forming a part of said frame, a rim of clothwithin said frame, a

circular space filled with sand within said rim of cloth, another rim of cloth within said sand space, a rim of filtering-paper within and adjacent to the second rim of cloth, a third rim of cloth within and adjacent to said filteringpaper, a screen supporting said inner rims, all of said rims secured at the ends by suitable means, a space within said rims for filtered water and a tube in said space through which the water may be withdrawn, substantially as described.

In witness whereof I have hereunto subscribed my name, this 17th day of August, 1898, in the presence of two witnesses.

CHARLES F. HOYT.
